voxl-docker-mavsdk-python build issues

[Eric Katzfey]

@Alexander-Saunders The heartbeat counter is the amount of heartbeat messages being sent out, not received. So you are not getting anything on the serial port.

@Alexander-Saunders Also, take a look at this: https://www.reddit.com/r/linux4noobs/comments/lu1plx/hi_i_get_this_authorization_required_but_no/

[Eric Katzfey]

@Alexander-Saunders Definitely looks like a permissions issue of some sort in your system.

[Alexander Saunders]

@Eric-Katzfey Are you suggesting giving the file/repo permissions with

xhost si:localuser:root

Also we are using the FDTI cable provided with the ESC AND USB C to A to connect to host.

[Eric Katzfey]

@Alexander-Saunders I'm only suggesting that there is a permissions problem of some sort. I don't see that on my machine so just trying to figure out what is different in your environment.

[Alexander Saunders]

@Eric-Katzfey I tried giving permission to user with no change.

[Alexander Saunders]

@Eric-Katzfey Is it possible to see a picture of your terminal of the commands you sent?

@Alexander-Saunders iris_hitl.sdf is part of the docker image so it will be the same.

@Alexander-Saunders We have quite a few customers using HITL successfully and they are using the instructions in the document so I'm thinking there is something in your environment that is causing the issue. Do you have access to a different Linux machine that you can use?

[Alexander Saunders]

@Eric-Katzfey Update:

We switched some of the wires for the FTDI cable and now receiving data. We went back to following the HITL docs along with https://forum.modalai.com/topic/3511/serial-port-closed-and-other-hitl-errors/9 . We have the drone running in HITL via QGC and running the voxl-px4-hitl command. Despite this, gazebo is still not showing the drone or connecting. Could the issue possibly be with the Dockerfile that reflects bionic instead of focal since that had to be changed for the image to be pulled? We also tried running ./run-docker.sh within the directory and received docker run --help.

[Eric Katzfey]

@Alexander-Saunders Looks better now. What does the dsp_hitl start command look like now? Seems like it is setup for VIO only.
